Swagman Quad Platform Bike Rack Reviews

I am looking for a new bike rack for 4 bikes. A similar Thule or Yakama rack will cost me around $700. Quad 2+2 cost me about $450 so I decide to take a chance on this one. Another selling point of the Quad 2+2 is I can use it as 2 or converted it to 4 bikes. The box came in weighing 98 lbs, heavy. Solid build right out of the box. Instruction to put the rack together is terrible. I basically put the rack together by looking at the picture on the box. So far the rack works good.
